3.5 Adjusting limit switch
-
Manually position the door wing completely open and fasten
the limit switch brackets [L] onto the rack so that the lever
limit switch exceeds the bracket’s length by approximately
2/3. Repeat the operation with door wing completely closed.
- After having performed a certain number of operations,
adjust the position of the limit switch bracket [L] so that the
gate will stop about 20 mm before the opening and closing
stops.
Note: (Only for Cross7EH) the limit switch kit is optional and it is
used to stop the gate before the opening and closing stops.
When limit switch is present, slow down is carried out at
maximum power to overcome possible friction.
3.6
Operation by encoder
The Cross7EH does not require limit switches because it has an
encoder. Stops must necessarily be installed. The gate deceler-
ates automatically in proximity of the stops.
Attention: upon reaching the opening or closing limit stop, the
gate performs a brief disengaging maneuver (moving reversal)
to facilitate the manual release of the geared motor.
3.7 Cross7EHTC installation (only for Cross7EH)
Disengage the gearmotor (see OPERATING INSTRUCTIONS).
Remove the pinion [14]. Fix the pinion-holding plate to the
gearmotor. Fit the pinions as shown in the figure. Manually route
the chain through the pinions. Fix the cover plate.
Attention: with chain fitted, the gearmotor direction of rotation
is reversed.
3.8 Chain installation
-
Set the gate in the open position and fasten brackets [G]
to the wing as shown in figure.
-
Connect the chain previously installed on the gearmotor to
the tie rod [H] and fasten it to the bracket [G].
-
Secure the bracket [G] onto the opposite side of the gate.
Connect the chain to the tie rod [H] and secure it to the
bracket [G] (cut off excess chain).
Note: with the gate in complete opening and closing po-
sition, check that the distance between the centre of the
pinion [Y] and the tie rod [H] shown in figue is respected.
-
Finally, firmly secure the gearmotor by means of nuts [D].
-
Tighten the chain by means of tie rods [H].
-
Lightly lubricate the chain and pinion after assembly.
